Title: Improvements in and relating to autographic registers
IPC: B41L5/04
Filed: 1936-05-05
Abstract: 461,528. Autographic recorders. LAMSON PARAGON SUPPLY CO., Ltd. May 5, 1936, No. 12690. Convention date, May 10, 1935. [Class 106 (i)] An autographic recorder is provided with one or more strip controlling and tensioning elements that are moved out of strip-engaging position by spring means when their supporting frame is moved from an operative to a strip-threading position. The invention is described. as applied to an autographic recorder having feed-mechanism for zigzag folded strips of the kind described in Specification 341,973. As shown in Fig. 2, the strips S pass from a supply compartment over guides 32 and a platen 17 to the feeding mechanism (not shown), the strips being pressed against the guides by bristles 29 projecting from rods 30. The bristles are normally forced toward the strips by arms 35, Fig. 3, secured to the reduced ends 34 of the rods 30, screws 39 in the arms abutting with their lower ends against corrugations 41 in a plate 36, slidable on a frame 21 that carries the guides 32 and rods 30. This frame 21 is normally held in the position shown by a spring catch 27, Fig. 2, but is rockable clockwise about a spindle 24 on the platen to enable the strips to be threaded between the guides and bristles. The rocking of the frame from normal position frees an extension 45 of the slide 36 from a vertical wall 19 of the platen and permits the slide to move to the right under the action of a spring 43, whereupon the arms 35 are rocked counterclockwise by the corrugations 41 and rock the bristles to permit unobstructed threading of the strips. The guide frame is adjustable laterally of the strips, the spindle 24 being mounted for this purpose in brackets 25 projecting from a slide mounted in the wall 19 of the platen. To permit ready access to the supply compartment, the platen 17 is hinged to the machine frame 15, Fig. 2, by arms 16.

Title: Improvements in and relating to means for protecting the windings of dynamo-electric machines
IPC: H02H3/26

Abstract: 359,506. Protective cut-out arrangements. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 24, 1930, No. 12695. Convention date, April 24, 1929. [Class 38 (v).] To avoid lack of sensitiveness due to the fact that the resultant voltages 8, 9 across the two halves of a phase of a dynamo-electric machine, consisting of coil groups of which the individual voltages are represented by the vectors 1 .. 6, are out of phase, comparison of voltages is made between resultant phase voltage 7 and the resultant 10 of the group voltages 3, 4, which voltages 7, 10 are normally in phase with one another. The voltages 9, 10 are fed, respectively, to two normally-opposing windings of suitable turns of a transformer, a third winding of which is energized to operate a release coil and/or indicator when the transformer balance is upset by a fault in the phase in the machine. The windings of a wattmeter-type relay may alternatively be fed respectively, by the voltage 7 and that of the third winding of the transformer, so that higher harmonics appearing in the latter voltage, but not, due to vectorial addition, in the voltage 7 are unable to effect undesired response of the protective arrangement in normal conditions.

Abstract: 775,399. Printing surfaces. BOBST & FILS SOC. ANON., J. May 3, 1955 [May 14, 1954], No. 12761/55. Class 100(2) Apparatus for mounting a curved stereo plate 1 upon a,cylinder comprises a cylinder 2 having reference markings 5, 6 thereon enabling the angular position thereof in a frame to be fixed, the frame being provided with a slide provided with reference markings enabling parallel rods 8, 9 to be moved along the cylinder 2 whilst maintaining their axes radial in relation to the latter. The rods 8, 9 are normally maintained at a distance from, but slidable axially towards the cylinder 2. The ends of the rods adapted to come into contact with the surface of the cylinder are so shaped as to permit of their introduction into locating holes 3, 4 in a curved stereo plate which is to be adhesively mounted on the cylinder. The rods 8, 9 are individually adjustable in a support, shown diagramatically in Fig. 1 and which is provided with a scale 10, 11 so that their position may be accurately determined. For circumferentially locating the cylinder so that the marks 5, 6 register with the rods 8, 9, a scale 12, 13 is provided, also shown diagramatically in Fig. 1. The plate engaging ends of the rods 8, 9 are telescopically mounted in the rods so that the plate is first mounted on the rods as shown and is then, on release of the telescopic parts of the rods, pushed on to the cylinder 2 to correct position. For applying pressure to the plate 1 to secure better adhesion to the cylinder 2 a cylinder 47 may be provided. The cylinder 47 may also be provided with a leading-edge clamp for a plate so that the cylinders 2 and 47 may co-operate to bend an initially flat plate.

Filed: 1927-06-30
Abstract: 273,666. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). May 12, 1927. Sodium or potassium chromates and aluminates; alumina.-Chrome ore is heated with bauxite or other aluminiferous materials in the presence of alkali carbonates or mixtures forming such carbonates at decomposition temperature, so that on lixiviating the product, a solution of chromates and aluminates is obtained. Caustic alkali lye, particularly potash lye, may replace the alkali carbonate. Lime may be added. Alumina may be precipitated after removal of silicic acid by carbon dioxide, and the soda later crystallised, leaving the alkali chromate solution. Silica is separated as sodium aluminium silicate, which is precipitated more readily by boiling under increased pressure.

In a revolution counter, an indicator shaft 12b is driven by an input shaft 14 through a worm and wheel 14a, 14b, a shaft 12a, and an electromagnetic clutch 13, an arm 16 carried by the shaft 12b opens a microswitch 15 to disengage the clutch through control means upon predetermined rotation of the indicator shaft 12b from a datum position, and a coil spring 18 secured to a drum 22 on the indicator shaft and to the counter casing and wound up during said rotation returns the indicator shaft to the datum position, the re-engagement of the clutch being sufficiently delayed by a conventional delay mechanism 17. A stop 24 adjustably positioned on a fixed scale 20 lies in the path of a pointer 19 carried by the indicator shaft. Alternatively the stop may be fixed in the counter casing and the indicator scale mounted for rotation with the indicator shaft. In operation, the stop shown is suitably positioned on the indicator scale and the spring 18 moves the pointer into abutment with the stop. Clutch engagement effects rotation of the indicator shaft until the pointer reaches zero scale position when the arm 16 opens the switch 15 to disengage the clutch. The pointer is returned by the spring against the stop during which return the delay mechanism maintains the clutch disengaged. The delay mechanism is variable to provide a delay for all scale settings.

Abstract: 245,657. Wade, H., (Soc. d'ElectricitÚ et de MÚcaniques ProcÚdÚs Thomson-Houston et Carels, Soc. Anon.). May 18, 1925. Cylinders receiving liquid fuel.-A combustion chamber f, separated by a restricted passage g from the cylinder, is scavenged by air compressed by an auxiliary pump k to a higher pressure than the main charge of scavenging air, which enters through terminal ports c. The compressed air from the pump k enters the combustion chamber f through a small fluid pressure actuated valve i, and is stored during the intervals between scavenging periods in a reservoir p. The air enters the reservoir p through a small orifice o, the object of which is to prevent admission of any appreciable quantity of air from the pump during the scavenging period, in order to ensure the closing of the valve i during the period of opening of the main scavenging ports c. If supercharging of the cylinder is desired, the reservoir p is omitted, and the size of the pump k increased ; air will then be admitted through the valve i until the pressure in the cylinder is equalized with that of the auxiliary scavenging charge, after the commencement of the compression stroke.
